BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention relates to a portable flammable gas generatingdevice which provides flammable mixture of hydrogen and oxygen.

(2) Description of the Prior Art

A conventional way to get flammable gas is natural gas which is suppliedby the natural gas company and delivered via pipes connected between theusers and the natural gas tank of the company. The natural gas can bedangerous because of carbon monoxide which can be produced when thecombustion of the natural gas is not completed and such carbon monoxideis harmful to people. Another potential risk is that the natural gas isdelivered at a high pressure in the pipe and once the pipe leaks, thegas is flammable. FIG. 6 shows a conventional flammable gas generatingdevice which includes a hydrogen generating device 7 which is composedof an electrolytic tank 8 in which water is filled, a mixing tank 9 anda soldering gun 91 connected with the mixing tank 9. The hydrogen andoxygen are produced by the electrolytic processes to the water and thehydrogen and the oxygen are sent to the mixing tank 9. The mixture isflammable and can be used with the soldering gun 91.

However, the conventional energy generating device occupies a lot ofspace and heavy which is not convenient to be carried. Besides, theelectrolytic process requires a lot of electric power which increase thecost of the alternative energy.

The present invention intends to provide a portable flammable gasgenerating device which is in a form of a casing in which a hydrogensource and an oxygen source are received. The hydrogen and the oxygenare mixed together with a coolant and the mixture is delivered to a gasburner for use for outdoor barbecue.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 to 4, the flammable gas generating device of thepresent invention comprises a casing 2 having a top cover 28 pivotablyconnected to a top of the casing 2 and a handle 21 is connected to thetop cover 28 so that the casing 2 can be conveniently carried. A sensorunit 22 composed of a thermometer 221 and a level gauge 222 is connectedto a side of the casing 2. A receptacle 24 is connected to the casing 2and located away from the sensor unit 22. A plurality of apertures 23are defined through the wall of the casing 2 and located beneath thereceptacle 24. A control panel 14 is connected to the casing 2 and athrough hole 26 defined through the casing 2 through which an outputpipe 112 as shown in FIG. 5 extends. A separation board 27 is receivedin the casing 2 and defines an inner space of the casing 2 into an upperspace and a lower space.

A mixing tank 11 is located at the lower space and includes an innerspace 111. The output pipe 112 is connected with the mixing tank 11 andextends through the through hole 26 so as to deliver the mixture of theflammable gas to a burner 3 a shown in FIG. 5.

A hydrogen source 12 is located in the upper space and has a hydrogeninput pipe 121 connected thereto. An oxygen source 13 has an oxygeninput pipe 131 connected thereto and a coolant pipe 15 is located in theupper space and connected to a coolant source. The hydrogen input pipe121, the oxygen input pipe 131 and the coolant pipe 15 are respectivelyconnected to the mixing tank 11, and the hydrogen source 12, the oxygensource 13 and the coolant source are respectively connected with thecontrol panel 14. The user may check the conditions of mixture by lightsof the control panel 14. A plurality of ventilation holes 25 are locatedon two sides of the casing 2 and a plurality of casters 29 are connectedto an underside thereof.

A receptacle 24 is connected to the casing 2 and located away from thesensor unit 22, and the receptacle 24 is connected with the oxygensource 13 which can be driven by AC current when needed.

The mixing tank 11 has an inner space 111 and a tubular member 113 isreceived in the mixing tank 11 and defines the inner space 111 into afirst space 114 outside of the tubular member 113 and a second space 115within the tubular member 113.
